Update 10.12.2 BeamNG v0.32 Team Mode
First, I want to say thank you to everyone who has continued to play, support, test, and give feedback on Demolition Derby: The Fairgrounds. I really appreciate everyone’s patience and continued support while this update was being worked on.
A big part of this update was the derby AI. This ended up being one of the largest reworks I have done for the mod. I rewrote the AI several times, tested different systems, and kept tuning it until the cars felt more competitive, aggressive, and realistic in a derby. Some versions worked well in certain situations but not others, so it took a lot of trial and error to get the AI to a place where it felt solid across different tracks, arenas, and vehicle counts.
I feel like the AI is now in a much better place. It should be harder to beat, better at recovering when stuck, better at finding targets, and better at handling walls, corners, clusters, pits, and different arena shapes. Team mode also added another layer of complexity, so the AI now has to understand teammates, opponents, and how to avoid stacking on the same target.
Along with the AI work, I also fixed a lot of smaller bugs that I found while testing, including a texture issue that had been around for quite a while. This update also includes the BeamNG v0.32 BX vehicle changes, rebuilt derby configs, team roof signs, new debug tools, and several track and scenario fixes.
I know many of you support the game monthly, and I do not take that for granted. I want these updates to be worth the wait, and my goal with this release was to make a meaningful improvement to the way the derby actually plays, not just add a few small changes.
Thanks again to everyone who has stuck with the mod and helped make it better. I hope everyone enjoys the new changes, and I’m excited to see how the new AI and team mode feel in actual derbies.Update 10.12.2 BeamNG v0.32 & Team Mode
********************************************************************************************************
Team Mode:
1. Team mode is now available in the scenario menu — assign drivers to teams, configure team names/colors, and run team derbies with team scoring on the end screen.
2. Roof signs now display team colors (outline, stripes, and lettering) so you can tell which team a car is on at a glance. Derby Lands logo added to roof signs.
3. AI targeting updated for team play — opponents are prioritized, teammates are avoided, and tag-team pass lanes help spread hits instead of stacking on the same target.
Derby AI (major update):
4. Completely rebuilt demolition derby AI logic — improved targeting, attack commitment, wall/corner recovery, cluster escape, and overall aggression. This was a large rework and the main reason this release took extra time to finish.
If you prefer the older derby AI, you can still enable it from the Settings menu by selecting Use Original Derby AI.
Please note: the original derby AI does not support Team Mode. Team Mode requires the new AI system it will auto load the new system.
The screenshot below shows the original derby AI.

5. Added jam detection and ESC (escape) logic so AI cars can break free when stuck in traffic, pinned along walls, or bunched up in a cluster.
6. Arena awareness improved — circular arenas, four-corner quads, and custom arena shapes are supported for wall boundary and pit detection.
7. Split AI support code into modular extensions (arena shape, pit detection, and debug overlay) for easier tuning and troubleshooting.
AI Debug:
8. New menu option: Enable AI Debug Mode — shows in-world AI overlays (velocity, aim, state) and opens the Derby AI Debug app so you can watch what the AI is doing and change settings on the fly during a derby.
9. AI Debug can broadcast config/state changes to all cars in the heat. Bind "Green Derby: AI Debug Off/On" in Options > Controls (advanced) to toggle overlays with a key.
BeamNG v0.32 / BX Vehicles:
10. Migrated Ibishu Coupe to Ibishu BX-Series for BeamNG v0.32 compatibility.
11. Rebuilt all BX derby configs with correct steel wheels (removed race slicks, wings, and aero parts).
12. Added the derby driver model to BX vehicles.
13. Legacy coupe class selection automatically maps to bx in menus and scenarios.
Tracks, Scenarios & Fixes:
14. Fixed flashing ground textures on some tracks (decal data updated for current BeamNG format).
15. Improved vehicle extension loading with staggered spawn timing to reduce load errors on large fields.
16. Fixed arena waypoint / boundary detection on several tracks. Circle arenas and four-corner arena layouts now work correctly with wall boundary logic.
17. Updated Mini Mania GearGrinder99x mod logo image in the vehicle mod menu.
18. Various menu and track compatibility fixes carried over from the team mode and AI updates.19. The installer has been updated and is now code signed. This should help Windows recognize it as trusted and reduce security warnings during installation.https://www.patreon.com/posts/diecast-derby-117116950/
